17 Claims.

The objects of this invention are:

First, to provide an improved device for printing or engraving letterheads or the like on webs of paper and for severing said letterheads whereby the production of said letterheads on a single press may be speeded up.

Second, to provide such an apparatus in which a heavy press may be operated at a relatively slow rate of speed while a single feeding and cutting means can operate to feed the web and sever the letterheads at a relatively high rate of speed whereby there is a speeded up production with a great reduction in the wear and tear on the press.

5 Third, to provide such a device using the ordinary intaglio press with a light, fast operating, feeding and cutting mechanism for feeding a web to the press.

Fourth, to provide such an apparatus in which 10 pairs of dies print two or more letterheads at one operation of the press and in which a single cutting and feeding mechanism is employed.

Fifth, to provide such an apparatus in which the full printing capacity of a large sized press can be used to print a plurality of letterheads at a high rate of speed.

Sixth, to provide such a device in which four letterheads may be printed simultaneously at one operation of the press.

Seventh, to provide such an apparatus in which a split fountain may be used so that four separate letterheads of different design may be printed at one operation.

Eighth, to provide such an apparatus in which 5 there is a saving in operating cost due to the use of a single die wipe.

Ninth, to provide such an apparatus that can be operated at a saving due to the arrangement of the dies therein to permit inking and wiping O with a minimum ink consumption.

Tenth, to provide a method of printing letterheads or the like by means of which the printing press is saved from wear and tear due to fast operation while speeding up production.

Eleventh, to provide such a method for any printing.

Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow.

Preferred embodiments of my invention are illustrated in the accompanying drawings, in which:

Fig. 13 is a detail sectional view of the split fountain and inking rollers suitable for use in my apparatus.

Fig. 14 is a front elevation view of a modified form of my apparatus in which two dies are used with a single feeding and cutting'mechanism.

The parts will be identified by their numerals of reference which are the same in all the views.

1 is a printing press of usual design having a die holder 2 with dies 3 that will be later described. 4 is the fountain of usual design comprising a pan 5 with roller 6, inking roller 7, knife 8 for scraping ink from the die, and a paper die wipe 9 running over the member 10 which is actuated as is usual in such presses to wipe the die after it has been swung to the position indicated in dotted lines in Fig. 11 for inking and is being swung to the printing position by means of the mechanism 11 which is of conventional design. A single die wipe is provided and the fountain 4 may be a single fountain or may be a split fountain such as shown in Fig. 13, having its pan 5 divided by partitions 12 in which various colors of ink may be placed.

The inking roll 7 may be divided into separate rolls 13, each adapted to take the color from separate rolls 14 in the pan 5. I have not deunder through which a paper web 19 passes. The

web 19 then passes through the opening 16 in the counter over the rounded edge 1'7 thereof and to the feeding mechanism. The opening is so arranged that it comes between the dies 3.

In the modification shown in 1, the paper webs 19 are supplied the apparatus from two rolls 20. Auxiliary feeding means comprising friction rolls 21 and 22 take the paper from the role allowing it to hang in a loop 23 between the rolls arid the press so that the main feeding means, which will be described later, can pull the web through the press without any tension so that the web will lie fiat on the counter at the time of printing.

The dies 3, here shown as four in number, are mounted on the die holder 2 in pairs. The pairs are in spaced relation as shown in Fig. 2 and the dies of each pair are in opposed relation as can be seen from Fig. 5. In Fig. 5 I have shown the paper web as printed with four separate and distinct designs of letterhead. If a large order of letterheads is going through, it would be desirable to provide four identical dies. If smaller orders are being run on the press, it is desirable to set it up as shown to print four separate letterheads, as shown in Fig. 5.

The dies are set up to print transversely of the web with the printed letterheads parallel and in opposed relation as shown. The dies so arranged are swung back as shown in Fig. 14 for inking. .The die wipe is so arranged that it wipes the four dies simultaneously, the motion of wiping being from one side of the die to the other. This arrangement of dies for printing and the wipe 9 therefor makes it possible to utilize the full capacity of the press in printing while using a minimum amount of ink for the inking and a single width of die wipe satisfactorily wipes the four dies simultaneously, effecting a saving in ink and die wipe thatis very material. As compared with inking and wipingfrom top to bottom of the die, it will be seen that less ink is wasted on the non-printing part of the die and that the side to side wipe, which is the long way of the die for letterhead printing, effects a saving in die wipe because a narrower portion of the wipe is used for each operation, while the length of the wiping stroke is the same. By using a split fountain, each letterhead can be of a different color if desired.

At each side of the apparatus shown in Fig. 1, I provide a main feeding apparatus 24. These are identical and each one feeds a single web of paper and severs the letterheads from the end thereof. The device comprises a base 25 supported on posts 26. Longitudinal side members 27 and 28 are provided. and are connected by a cross bar 29 on which is supported a fixed knife 30. 31 is a reciprocating cut-off knife carried by a knife holding bar 32 that is reciprocated in vertical guides 33 connected by a cross bar 34. The knife 31 and the bar 34 are connected to toggle arms 35 and 36. The toggle arms are arranged in pairs and are connected at their central pivot points 3'7 by a bar 38 horizontally disposed and normally pulled to the top of Fig. 6 by a spring 39 to raise the knife 31.

.A lever 40 actuated by cam 41 on shaft 42 operated by bevel gears 43, 44, from the drive shaft 45 of the apparatus operates the bar 38. 46

and 4'1 are a pair of plates forming the feed table. A flexible guide blade 48 secured to the printing press extends above and parallel to the plate 46 and rests on the web of paper with gentle pressure while the web is being advanced. The plates 46 and 47 are spaced apart at the center to accommodate holding and feeding jaws.

The feeding jaws are carried on a reciprocating slide 49 reciprocating in slideways 50 formed on an extension of the side member 27. These jaws comprise a relatively fixed jaw 51 bolted to slide 49 having a suitable disk-like engaging portion 52 projecting upwardly between the plates 46 and 47 and on a level with the upper surface thereof. The upper movable jaw 53 is pivoted to a lateral arm 54 and is provided with an engaging disk 55 to cooperate with the disk 55'. The movable jaw 53 is provided with an upwardly extending arm 56 provided at its upper end with a stud 5'? on which a tension coil spring 58 is mounted, connected to a stud 59 on the lower jaw member 51, whereby the jaws are normally held in engagement by spring pressure.

The jaws are operated by a cam slide 60 dis-1 posed in ways 61 on a bracket 62 carried by the slide 49. The end 63 of the slide 60 projects downwardly to be engaged by trip stops 64 and 65 carried on the slide 66 at opposite ends thereof. The slide 66 is supported on brackets 67, 68. The slide 66 is pulled normally forward by tension spring 69, see Fig. 9. The slide 66 is provided with a downwardly projecting cam follower finger '10. This finger 70 is reacted upon by cam '71 which, in cooperation with spring 69, causes the bar to reciprocate to actuate the trips 64 and 65.

The slide 49 is provided with an car '72 provided with a pitman '73 connected to the upper end of the lever '74. Lever 74 is pivoted on the base at '75 and is operated by a pitman '76 that is connected at 77 to the cam rocker '78. The cam rocker 78 is operated by the cam '79 on the shaft 80, and is so timed that there is a short dwell at each end of the feed stroke during which period the feed jaws operate.

The cam 71 operates upon the slide 66 to actuate the feed jaws to open or close the same while the said slide is at rest at each end of its travel. By the operation of the machine, the web of paper is evenly grasped and released by the feed jaws while the jaws are relatively at rest in relation thereto.

The holding jaws are supported on the opposite side of the machine from the feed jaws. They comprise a fixed jaw 81 and the movable jaw 82. The fixed jaw has an engaging disk, the upper surface of which is level with the feed table top and stops are carried on the slide 93 and have the adjusting screws 94 and 95 to permit close regulation of the operation of the holding jaws. The slide 93 is supported in the brackets 96 and 97 and has a downwardly projecting cam follower finger 98 that is reacted upon by the cam 99 which actuate the trip stops at the end 'of the feed stroke. These jaws are timed to be opened to permit the paper web to advance when the feed jaws carry the same forward and are closed to hold the paper while the feed jaws are opened and are being carried back to the point of beginning.

By use of the apparatus shown in Fig. 1, it is possible toadjust the feeding stroke of the apparatus so that letterheads of different length can be printed at the same time, those illustrated to the left of Fig. 3 being shown as short lengths and those to the right as a longer length. When the sheet of paper has been cut from the web 19 as indicated in the diagram in Fig. 3, there is a small, endless conveyor 100 that conveys the sheet to theendless conveyor 101which conveys the same through the drier 102, which may be heated in any suitable manner. The shaft is provided with a sprocket 103 over which a chain 104 operates. The feeding and cutting mechanism is driven from shaft 30 by the sprocket 105, which is on a shaft of the printing press 1. The sprockets 103 and 105 are in such ratio that one revolution of sprocket 105 drives the sprocket 103 two revolutions, so that the feeding and cutting mechanism operates twice to one operation of the press. The feeding and cutting mechanism is timed to feed and out between impressions by the press, andthe feeding and cutting operation is completed twice in the interval of time in which the dies are being inked and wiped.

The operation of the feeding and cutting means is described in my co-pending application Serial No. 612,678, filed May 21, 1932, for Means of feeding webs of paper to printing presses, and I will not describe the operation in detail as it is there sufficiently described.

It will be understood that the specific construction of feeding mechanism is simple and inexpensive and can be run at a comparatively high speed. The press is of a heavier construction and cannot be operated at such high speed. The printing time at the lower speed is much superior to that done at high speeds and the working parts of the press are better preserved by running the press slowly.

The cutting and feeding mechanism is of a cheaper construction and can be replaced at considerably less cost than the press.

It will be understood that the arrangement of printing two letterheads in opposed relationship across the web in one operation and the timing of the feeder and cutter to feed and out twice, one of the cuts being between the opposed letterheads, makes it possible to speed up the printing without the wear on the press caused by fast operation and without the necessity for providing more than a single feeding and cutting means for each web of paper.

The use of the double arrangement is highly advantageous in utilizing the full capacity of the press in letterhead printing. Other sheets can be printed with the resultant saving on the press.

In Fig. 14, I have shown a printing press which is identical in construction with that shown in Fig. 1 except that only two dies 300 are used and the counter 1500 is of conventional construction. The auxiliary feeding mechanism at the left of Fig. 11 is similar to that shown in Fig. 1 and the feeding mechanism is identical with that shown in Fig. 1, so they need not be detailed. In this adaptation the savings resulting from the opera- 3 tion of the press at low speed while the cutter and feeder are operating at double the speed are present.

The press has the same inking and die wiping 1 arrangement and the saving on ink and die wipe through having the dies disposed so that they are wiped simultaneously from side to side, which is the long way of the die, is effected as in the other modification.

I have shown the mechanism in the specific form developed by me which has proved highly effective in use. Those skilled in the art will understand that, although my specific form of feeding and cutting mechanism is highly desirable in the combination, because of its cheapness, it need not necessarily be used, and that any feeding mechanism timed to feed and out twice to one operation of the press would have most of the advantages that are derived from the'use of my specific mechanism. I desire to claim the entire device and also the specific portions thereof and I also desire to claim the invention broadly as pointed out in the appended claims.
